Question about 1990 Toyota Celica

1 Answer

Low idle/no acceleration.

Have a '91 celica gt w/ milage expected of that year. Engine will only go to about 3-400(yes..hundred) rpm. and doesnt change when pushing the gas pedal. I hooked up another fuel pump directly to the fuel rail, therefor bypassing the filter and I get the same results. The pump is also fed directly from a fuel can. It will putter for about a minute then stop. I also have no water in the rad. Is there a switch that limits rpm's when low on water? I'm stuck and need help. Thnx.
P.S. I did check relays and fuses. they seem to be ok.

Hello, it could that the timing belt is worn and slipped on the pulleys so I would go there first and make sure the cam timing is aligned and inspect the timing belt.

SOURCE: 4 cyl Engine starts and idles ok...give it throttle and it dies

I need to get a clear mental picture of what exactly is happening.

With this said, you stated that the car "runs fine" until warmed up.

Q: When you start the car when cold it idles fine?
Q: If you allow the car to idle until "fully" warmed does the car stall?
Q: As the car begins to warm up, Does the RPM fluctuate abnormally?
Q: Does the car Only stall when you press on the gas pedal or does it stall just sitting and idling in addition to pressing the gas pedal?
Q: If you can drive it while cold does the car stall during acceleration when warm or only at Stop Signs / Lights?
Q: If you wait 20min or so, can you start the car again?
Q: How many miles are on the car?

SOURCE: I have 1990 Celica GT 2200. no spark to plugs/power to fuel pump

need to change rotor and cap , and might as well change wires and spark plugs if its due for a tuneup! yeah have your ignition control module check if it doesn't start after replacing every thing else.

SOURCE: 91 mr2. no power 2 the fuel pump. checked relays

When you say you have checked the relays and fuses i hope you checked to see if they have power getting to them. Besides that The most frequent cause of problems is simply a bad contact in wiring connectors. Always check that connections are secure. Inspect the contacts for bent pins or corroded. You may also want to inspect the ground side of the circuit. If everything checks out then you have a bad fuel pump.

Sounds to me like the fuel pump is worn out. They DO wear out. And even though they seem to be working, the brushes in the electric fuel pump may not be contacting all the commutator, thus making the pump weak. It may start the motor but can't maintain normal running pressure (27-35psi). Have you run the car out of gas shortly before this problem surfaced? If you have then it's your fuel pump. It was damaged when the tank ran dry. Even though the pump may seem to be working, it's still badly damaged and needs to be replaced.
Just as Matmenzies has stated, get a fuel pressure gauge and test the pressure. I'd start with a complete check of all your vacuum lines. Check for cracks on the vacuum hose that connects to fuel pressure regulator on the fuel rail. Also, if you can, get a hand operated vacuum pump to check the regulator. If you can place a vacuum on the regulator and it holds, I'd say move on the fuel pump and check it.
BTW, if the fuel filter has been changed, you may want to check to see if it was installed backwards! Some fuel filters are valved and will cause symptoms like this. However, this is an immediately noticeable mistake and you haven't provided enough info for me to say more. I'd pull it and check that it has any flow at all. You could have sucked in a big dirt ball and blown it right into the new filter, effectively stopping fuel flow. Then I'd blow out the fuel lines, just to be sure.
Start with these 2 things and post what you find. We'll go from there.

If the fuel pump operates with with a jumper at data link.That clears that the fuel pump is running.So check the EFI relay and the fuel pump relay. Now what is EFI relay:--- EFI Main Relay The EFI fuse supplies constant battery voltage to EFI main relay. The EFI main relay provides battery voltage to +B terminal of circuit opening relay (some models) and data link connector. Depending on model, EFI main relay may either be turned on directly by ignition switch or by M-REL terminal of Engine Control Module (ECM). The EFI main relay may also provide battery voltage to +B and +B1 terminals of ECM when ignition is turned on. The EFI main relay is located in engine compartment relay box. NOTE: Circuit opening relay is used on all models. Circuit Opening Relay Circuit opening relay controls fuel pump circuit. The Engine Control Module (ECM) receives an input signal at STA terminal when engine is cranking. Starter signal is also applied to STA terminal of circuit opening relay. Starter signal energizes circuit opening relay during cranking. Circuit opening relay then provides voltage to fuel pump or fuel pump relay.The circuit opening relay is grounded by ECM through FC terminal.Fuel Pump Relay & Fuel Pump Resistor .Fuel pump relay receives voltage from circuit opening relay and operates fuel pump. Fuel pump operating speed may be varied by Engine Control Module (ECM). When ECM grounds fuel pump relay, relay contacts close, and voltage is supplied through fuel pump resistor, to fuel pump. This changes fuel pump operating speed. ---------------------- As there are many other possibilities to check out of the mentioned procedure.But as you said fuel pump works with jumper wire and the fuel pump relay is replaced,on as per that i think the problem is the Fuel pump relay connections.The relay ground wire is connected to the ECM.If this wire is not connected properly or if this ground wire is got short or in-case not connected,then the ECM will not send signal to fuel pump relay to get started so it will not let the fuel pump start.But in jumper wire connection the relay is bypassed so no ground connection required and due to that fuel pump works. Thanks. Keep updated for any more query. You can rate this solution and show your appreciation

I have a1995 GEO prism it runs good but when I let off of the throttle it won't idle unless I keep my foot on the throttle


Clean the throttle body and idle air control motor. Just a cheap start. Could be the engine is old and tired.

Gas milage and idle rpm


new engine might already be experiencing "blow-by".
search for a manual and check compression values. then have a mechanic perform a compression test on your engine. if result is much lower than expected, then try replacing piston rings, valve guides, and valve seals

While driving my tachometer doesnt go straight to 0 when i stop. It stays around 3/4 close to 1. Is this a concern? 2001 acura cl type s


Hi Eveerei, If you're asking about the tachometer and not the speedo meter, that meter records the engine RPM speed and not the vehicle ground speed The tachometer at idle (when you stop at a traffic light, stop street or any other stop) should record an engine speed of about seven hundred to seven fifty revolutions per minute, at idle. It will increase in relationship to how hard you push your foot on the accelerator pedal. Hope this info helps you. Happy new year and regards John

Power steering does not work at low rpm


What is the idling RPM of the engine when this is happening? There are many different types of power steering systems out there these days on vehilcles. It would make it a bit easier if we had a little more information before we give you advice. Year, Make Model, Milage, ect...Any other known issues with vehilce? Yes, the most likely culprit could be the pump because as time goes on the internal pump compoinents start to wear down and the tolerances become to great and at low rmp it cannot keep the proper pressure needed to give adequate power assist to the steering gear.
Hope this helps
Sincerely'
Roger

I have a 91 Eldorado 145,000 the engine runs but sound like it about shut off, and when you give it gas it sound like it the catalytic converter is clogged. I just got the car and after reading you...


Sound like not all cylinder are contibuting and the reason it want to shut off is the RPM is to low. If the catalytic convertor is plugged as you accelerate youll hear exaust through the air cleaner and have no power. And yes a plugged catalytic will cause the engine to be rough and not to be able maintain proper RPM and thus the shut off. Inspect for a plug catalytic disconnect it look through it.and since it out start the engine is the rpm smoother , accelerate it does it seem to have more power, then you solved the problem.Also the cadillac has a Idle speed contol motor youll have to see if it nose can extend and retract this is important to maintain proper RPM

Bad acceleration


Your catalytic converter needs to be replaced. It's becoming clogged, and preventing your exhaust from escaping properly.

Surging and not shifting


change the transmission filter sounds like its clogged up. replace w/ name brand high milage transmission fluid. should fix you right up. if you take it to a shop you can ask to have the bands adjusted also, that should give you another 5- 10,000 miles on trans. maybe more. good luck

91 Toyota 22re sputters around 2500rpms


your throttle position sensor might me bad or out of adjustment. if it is out of adjustment then it can misfire all the way up to 3500 rpm.
i had a friend that had a miss fire at 2500 rpm. i adjusted the tpss right and the misfire went away. Check for engine codes by jumping TE1 and E1.
Your fuel filter may be dirty and restricting fuel to your injectors.
have your fuel pressure checked.
